g This invention relatesto electrical connectors and in particular is directed to a connector for carrying a bus bar and having a member adapted to receive and hold a plurality of conductors which distribute the current supplied by the bus bar. s

In my pending application, Serial No. 716,752, from which this application has been divided, I have shown an electroplating bench having a plurality of plating tanks and an electrical system comprising a bus bar held by readily assembled and easily demountable connectors, each of which is adapted to receive and hold a plurality of conductors whereby the bus bar current may be divided and distributed. The connector shown and described in the said pending application may be utilized in a variety of ways other than the specific manner therein illustrated. Such connectors provide a markedly improved and advantageous structure for securely carrying a bus bar and at the same time affording means for the ready positioning and fastening of a plurality of conductors which divide and distribute the current of the bus bar line.

Accordingly, it is among the objects of this invention to provide an electrical system which: is readily assembled and easily demounted; is sturdily positioned; and rigidly holds a bus bar, and affords means for connection therewith of a plurality of conductors which distribute the current from the bus bar line.

The foregoing and other objects of the invention will become apparent from the more detailed description thereof taken in connection with the accompanying drawings wherein Fig. 1 shows a connector in disassembled relationship embodying the principles of this invention.

Fig. 2 is a view in section of the connector illustrated in Fig. 1 showing the same as positioned on a support and carrying a bus bar.

Fig. 3 is a top plan View of a connector such as that illustrated in Fig. 1 showing four conductive rods leading away from the connector.

Fig. 4 is a top plan view of a connector such as that illustrated in Fig. 1 showing two conductive rods leading away therefrom.

Fig. 5 is another form of connector in disassembled relationship embodying the principles of this invention.

Fig, 6 is a view in section partially broken away showing the connector illustrated in Fig. 5 carrying a bus bar.

Fig. 7 is a top view of the connector illustrated lnFig. 6. a

The connector illustrated in Figs. 1 and 2cmbodies a member [0 made of conductive material such as brass or the like, having at its lower end a bore ll through which is passed a bus bar I2 and at its upper end a threaded portion l3. An insulating collar [4 which may be provided with a shoulder I 5 surrounds the member In. The connector is firmly Secured to a support it by means, or the nut ll which, when tightened, also serves firmly to hold the bus bar in position. ,If desired a washer i8 may be placed between the bus bar and the lower end of the collar [4 in assembling the unit. The nut ll and the member It may be provided with bores 26 and 2! respectively into which are inserted conductive rods, as for example 22, leading to the point Where the current is to be utilized. The nut ll may also be provided with threaded holes 23 for receiving set screws 2t to secure the inserted rods in desired positions. A plurality of holes 23 in the nut affords the advantage of enabling the operator to manipulate the set screws from a desired vantage pom An important feature of the connector is that the passageway or bore into which are inserted the rods 22 is so proportioned as to its diameter D that when the set screw of diameter d is inserted, the distance between the side of the set screw and the side of the passageway (D-d') /2, is less than the diameter d of the inserted rod or conductor; also that the diameter of the passageway or bore is so proportioned that it can take up to four rods, so that, when the set screw is tightened, all four of the rods position themselves ahead of the set screw.

The connector illustrated in Figs. 5 and 6 cmbodies a member 30 of conductive material such as brass or the like, having an upper end 3| which rest upon, or is positioned against, a support 32. The lower portion 33 of this connector is threaded as at 34 and slotted as at 35 to receive a bus bar 35. An insulating collar 37 (shouldered at its upper end if desired) is positioned between the support 32 and the bus bar. The bus bar is held in position by means of a nut 38. The bore or passage 46 of the connector provides a means for receiving conductive rods (similar to membars 22 in Figs. 3 and 4) leading away from the connector to the points where the current is used.

Such conductors may be securely fastened within the connector by means of set screws (similar to the screws 24 illustrated in Figs. 3 r

and 4) inserted in the threaded passage 4|. In this embodiment there is also shown the provision for bringing to the connector a source of 3 current supply through the threaded bushing 42 which is mounted within the threaded passageway 43. A lead line from the source of supply may be firmly secured within the bushing 42.

It will be evident that the embodiments described herein are illustrative of the principles of the invention and that it is possible to achieve the objects thereof by modifications in structural arrangement without departing from the spirit and scope of the invention and that the claims are to be understood as defining the invention as above set forth.

I claim:

1. A connector for use in an electrical circuit comprising in combination: an elongated, at least partially tubular conductive member provdied with a transverse cut out portion adapted to receive a first conductor positioned transversely of said partially tubular member, said partially tubular member being adapted. to be positioned on a support therefor; locking means comprising a clamping nut mounted on an extremity of said partially tubular member and an insulating sleeve surrounding said member and extending substantially throughout the length of said member for locking the partially tubular member, a support on which the said member is to be positioned, and the aforesaid first conductor in assembled relationship; an extremity of said partially tubular member having means to receive at least one second conductor; and means for locking said second conductor in said tubular member, thereby providing means for establishing electrical connection between the aforesaid first conductor and the aforesaid second conductor.

2. A connector in accordance with claim 1, wherein the cut out portion of the at least partially tubular member is a bore transverse the axis of said member.
